The purpose of this post is not to bash the GN, so please don't be offended if you chose differently than I did. Like you guys I waited a long time for the Galaxy Nexus. After messing with it and the Rezound I chose the Rezound. The main reasons I prefer the Rezound:
I prefer the crispness and natural colors on the Rezound's SLCD with more ppi to the GN's pentile SAMOLED (though the latter performs better in direct sunlight).
I prefer the camera on the Rezound. It's shutter is instant and the photos are sharper.
I prefer longer battery life on the Rezound (with the 2750 mAh extended battery)
I prefer the thickness and solid feel of the Rezound in my hand to the width and thinness of the GN.
I prefer the ability to install my 32 GB SD card on my Rezound making it a 48 GB phone to not being able to install a SD on the GN.
I prefer being able to mount the Rezound as a USB mass storage device as opposed to being unable to on the GN.
I prefer having a dedicated search button on the bottom right of the phone as opposed to having search be in a menu.
I found Sense to be more intuitive and consistent than stock ICS, and without suffering any sort of lag.
That being said, I would appreciate it if HTC did not include preinstalled 3rd party apps that I cannot uninstall. Not that it has noticeably affected the Rezound's performance, but I think the ability to choose what apps and features you want on your phone is important.
If you prefer pentile display to SLCD the GN is a phone for you.
If the quality of the camera isn't of high priority to you, then the GN is a good choice.
If 32GB is enough storage for you, and mounting the phone is not important, the GN is a good choice.
If you don't use the search function often or don't mind an extra step in getting to it, the GN is a good choice.
If you absolutely hate Sense UI and feel there will never be a way around that, but you love ICS then the GN is the only choice for you right now.
I hope this post is helpful to those trying to make a decision about whether to keep their phone or find another. I will add that I had the Razr and imho it is not in the same league as the Rezound or GN. On the Razr, the non HD screen and poor camera combined with atrocious battery life and uncomfortable fit in the hand makes it a phone that's only really good for showing people and saying "isn't it amazing how thin it is?"
